Issue:
Events not rendering due older implementation of fetchOrgEvents query
**Describe the bug**

fetchOrgEvents query being used in app is still on older implementation which requires recurrance field. The reccurance field support was removed from Talawa API in https://github.com/PalisadoesFoundation/talawa-api/issues/2107

**To Reproduce**
Steps to reproduce the behavior:

1. Login to a organisation.
2. Open Events tab.
3. No events are rendered due to failing query.

**Expected behavior**
The `fetchOrgEvents` query must return events as a result, all the events of organization must be rendered. 

**Actual behavior**
The `fetchOrgEvents` query fails, as a result no events are rendered.

**Screenshots**
